Abstract
An apparatus provides an electronic signal in response to at least one of an applied force and an applied torque. The apparatus includes a detection device that detects movement of a movable member relative to a base, and provides the electronic signal, by driving a plurality of first sensor components. The detection device includes a control circuit having a first output that provides a digital control signal, and a first input for receiving a comparison signal, and a second output that provides the detection signal according to the comparison signal; a digital-to-analog converter having an input coupled to the first output of the control circuit, and an output that provides the drive signal in response to the digital control signal; and a measuring circuit having a first input coupled to the output of the digital-to-analog converter, a second input that receives a result signal from a plurality of second sensor components co-acting with the plurality of first sensor components, and an output coupled to the first input of the control circuit that provides the comparison signal, the plurality of first sensor components and the plurality of second sensor components co-acting with th…
